At home, Bill tells Liam that he's glad he acted 'more or less like a man' with Ivy. Katie's sure that she will be fine eventually. Later, Steffy arrives at Liam's. She informs him of her run-in with Thorne. He encourages her to unwind and repeats that none of this is her fault. He's sure that she knows that Thorne is just lashing out over what he lost. "I am never leaving you," she tells him. He wouldn't let her. They make out and go to bed.

At Forrester Creations, Ridge, Caroline and Thomas discuss Aly's death. Thomas feels his sister is paying a price. Ridge says it's through no fault of her own. Thomas argues to cover for Steffy, but Ridge isn't changing anything, even temporarily. Thomas will join the design team. He and Ridge spar verbally. Thomas comments that Ridge and Caroline together is 'bizarre'. Caroline asks what's bizarre about it. They assume he thinks Ridge is too old for her. Thomas says it's just kind of trippy. Talk turns to designing. Ridge wants him to show him something. Thomas tells him to make sure he wears his reading glasses and exits. Outside, Steffy wants to be involved in a project, but Liam thinks she's been through a terrible trauma and should take time off. He assures her there was nothing she could have done to prevent Aly's death - she slipped and fell. Steffy says it wasn't that simple. Liam asks what happened and Steffy walks him through it up to Aly attacking her with a tire iron. After that it all happened so fast. Liam assures her it wasn't her fault. Inside, Quinn, Wyatt, and Ivy are working when Thorne appears. He comments on his daughter slipping and hitting her head; to think she would die like that. Ivy looks like she wants to say something. Thorne complains about Ridge at the memorial service. Ivy thinks he was just upset for Steffy. Thorne comments that she's still alive. He still can't fathom that Aly slipped and now she's dead. "Tell me how that happened." Quinn remarks on the senseless death. Ivy and Wyatt tell Thorne that Aly loved him and spoke about him all the time. Thorne needs closure. "There has to be more." Quinn takes him outside. Ivy wonders to Wyatt how she can keep the truth from Thorne - Aly died because Steffy killed her. Wyatt argues that there would be repercussions. Ivy thinks Thorne deserves the truth. They debate about Aly; Wyatt says she was the aggressor and provoked it. Ivy says she only knows what she saw and Steffy lied to the police. She laments not being able to help Aly and bring her back. Wyatt says she's amazing for standing up for Aly, but she has to stop blaming herself. She asks how. Wyatt kisses her. In Ridge's office, Steffy is distracted. Ridge needs her leadership. He warns her not to answer questions from the press and to keep away from them. Thorne appears. Ridge says he's protecting Steffy. Thorne asks what about his daughter. "Who protected Aly?" Ridge says everyone feels terrible - he remembers what it feels like. Thorne doesn't have answers. He thinks Ridge trashed Aly at the memorial. Ridge says he told the family that they missed the signs of mental illness; she was a victim of it and made Steffy one too. Steffy tells Thorne that Aly tried to hit her with her car and attacked her. When she tried to defend herself, Aly slipped and fell. Thorne thinks something else must have happened. "Tell me!"

At the Forrester mansion, Ivy tells Steffy, "Aly died because of you." Steffy wonders if Ivy is implying that she's responsible for what happened to Aly. Ivy replies, "That's exactly what I'm saying." Steffy reminds her of the things in Aly's bedroom and that she tried to run her down and attacked her. Ivy questions Steffy's version that Aly tripped and died. "Is that your story?" Steffy angrily says she did nothing wrong. On the terrace, Wyatt and Liam lament Aly's death and remark on Thorne enduring such tragedy. Liam says he's had to keep reminding Steffy it's not her fault. Wyatt seems surprised. He asks if she's told him everything that happened that night. Liam says, "Everything she remembers." They talk about how none of this would have happened if Aly hadn't gone crazy on Steffy. Wyatt and Liam are both worried about her. Liam reminds Wyatt that Steffy will lean on him. Wyatt is irked that he's implying he would use this to hit on her. Liam knows he wouldn't do that. Wyatt muses that someone could blame Steffy for this. Liam is certain this isn't her fault. They rejoin Steffy and Ivy. Liam wants to speak to Ivy, so Wyatt and Steffy step out. Wyatt figures Liam is breaking up with Ivy. Inside, Ivy can't believe Liam is doing this at her cousin's memorial. She hisses at him to just go ahead and say he wants to be with Steffy. Liam says they've finally been given another chance. Ivy wonders if she was just a time filler and tells him if he wants to be with a woman with no conscience or moral center then good luck. Later, Wyatt tells Ivy he's sorry Liam did this to her today of all days. Ivy says she pushed Steffy, but she just kept lying. She watches the video again and talks about Aly. Wyatt says there was nothing more anyone could have done for Aly. "No one can see this video. Understand? It is way too dangerous."

At Forrester Creations, Caroline tells Ridge she wishes there was something they could do for Thorne. Ridge assures her they'll support him. They embrace as Thomas watches from the doorway. Caroline notices him. Ridge thanks him for being there. Thomas notes it's been hard on Steffy. Caroline hopes she doesn't blame herself. Thomas announces he's decided to move back for good. Ridge thinks it's a little sudden. Thomas gets defensive. Ridge asks if he's abandoning his job and notes they have no executive positions for him there. Thomas doesn't want one - he wants to join the design team. Ridge says the world doesn't work that way, but Thomas reminds him he backed him on the takeover. He says he's seen Caroline's stuff and it's pretty good, but he feels they'd like what he has to offer. Thomas thinks Eric will be thrilled and wants to know if he's in. Ridge agrees. Elsewhere, Liam tells Steffy he feels like a jerk for breaking up with Ivy today. Liam says it got intense and Ivy took shots at her character, but he knows she's right for his life. They kiss. Once alone, Steffy looks at a photo of Aly, cries, and has flashbacks. She thinks of Ivy saying it wasn't an accident.

At Forrester Creations, Steffy flashes back to the fight with Aly and to Ivy whispering, "She's dead." Liam joins her and talks about the last couple of nights being rough for her. Steffy keeps going over it in her mind. Liam hugs her. He says it could have been her out there dead on the road - they never know how much time they have left - he's really glad he decided to build a life with her.

At the Forrester mansion, Ivy looks at photos on the mantel and flashes to the night Aly died. Thorne, Brooke, and Eric appear. Ivy hugs Thorne. He doesn't understand how this could happen to his baby. Caroline, Wyatt, and Ridge appear. Caroline notes what a good friend Ivy was to Aly. Thomas arrives. Ridge is glad he made it. He says Steffy should be there soon. Thomas says he spoke to her and she seemed pretty upset. Katie and Bill arrive and have an exchange with Deacon and Quinn. They agree to try and get along for today. Near the terrace, Pam and Charlie tell Oliver he made Aly so happy. Oliver admits he could feel her slipping away. Pam says she's at peace now. By the fireplace, Caroline comforts Ridge, who says no parent should have to go through this. They wonder where Thorne is. Upstairs, Brooke and Eric watch as Thorne looks around Aly's room and sits on the bed to cry. They comfort him. Downstairs, Steffy and Liam enter. Ivy tells Wyatt it makes her angry that Steffy is there. Wyatt wonders if it's because of Liam or Aly. When Liam and Steffy approach, Ivy says everyone knows what happened to Aly, it just doesn't make sense. Thorne, Eric, and Brooke come down the stairs and Eric invites everyone to say what they'll miss about Aly. Pam and Charlie, Liam, Caroline, Ivy, Oliver, and Thorne each recall good times with Aly. Thorne thanks them all for making her happy and tells Aly's photo, "I'll always love you baby." He sobs. Ridge makes a speech about life. "We missed it. We all missed it." He asks Eric what the lesson is here and wonders if it's awareness or maybe acceptance. Later, Thomas tells Caroline he's sticking around; it seems like his sister needs him. Nearby, Thorne confronts Ridge about attacking Aly's memory - it was an accident. "Or was it?" By the terrace, Liam assures Steffy no one blames her. She takes a moment alone to look at photos of Aly and cries. Ivy appears. She recalls the horror of the night on the side of the road. She doesn't know how Steffy held it together. Steffy says she told the authorities what she could. Ivy warns she can't keep this all inside. "Deal with it. Deal with the consequences." Steffy asks what she means. Ivy says she knows Aly's death wasn't an accident.

Steffy enters the Forrester mansion shaking uncontrollably as she flashes to Aly's car coming at her. Liam appears. "What's wrong? Steffy, what's wrong!" Steffy gaspingly tells him about the flat tire and a car trying to run her down. "It was Aly." She says Aly was trying to reenact the scene where Taylor killed Darla. She says Aly attacked her. "I thought she was going to kill me and now she's dead." Thorne appears asking about Aly. He goes on about how he knows Aly has given Steffy a hard time and he's sorry for that. Steffy says it's okay and tries to tell him, but he keeps talking about taking Aly back to Paris for therapy. He just wishes she would answer her phone. Steffy says she won't. She tells Thorne that Aly lost it tonight. Thorne says Aly is a lot of things but she's not dangerous. "Where's my little girl?" Steffy finally tells him she's gone. Thorne shakes his head. "No, no." Steffy says it was an accident. "I'm sorry." Thorne leaves as Steffy protests it was an accident. Liam holds Steffy.

At the Forrester mansion, Maya is freaked out about what was found in Aly's room. Wyatt, Liam, and Rick don't blame her. Thorne arrives. Rick introduces him to his wife-to-be. Thorne tells Maya he admires her courage and is proud she's in the family. They discuss the fashion show. Thorne gripes about flying commercial and missing it. Rick says it's good he's there - Aly's in trouble. He explains that Aly's regressed. Wyatt and Liam chime in that it's getting worse. Maya says she's pulled away from Oliver, who is on assignment in Milan. Liam mentions the increase in outbursts at work. Maya says all her negative attention is focused on her and Steffy. Rick feels he's partly responsible and he's sorry. Thorne needs to know exactly what is going on. Thorne gets up to speed and grimaces. He asks if she's been seeing Darla. Liam confirms she's mentioned that. He is really concerned about her anger being fueled by isolation and close-mindedness...and she's taking it out on Steffy and Maya. Thorne laments that Aly has a loving nature but turns within and things go wrong. He vows to take her back to Paris with him and get her therapy. Rick and Maya step aside to discuss his magical proposal. Meanwhile, Liam and Wyatt wonder why Steffy can't be reached and try not to worry. Thorne hangs up - he's made arrangements for Aly with a doctor. Maya tells Thorne that Aly is lucky to have him.

At the Forrester mansion, Nicole thinks about her flirty interactions with Zende and smiles. He comes in from the pool to join her. Maya and Rick arrive. Nicole gushes about how well Maya did at the fashion show. They marvel over Julius agreeing to stay. Nicole says Ridge and Caroline were going home. They wonder where Steffy got to. Rick is sure she'll be there with a case of Tequila and a mariachi band before they know it. Upstairs, Ivy is concerned about violating Aly's privacy, but Liam declares that she needs serious help. He wonders about her therapist. Ivy reveals she stopped seeing one. Liam feels they all need to acknowledge how unstable she is. Downstairs, Rick wonders again where Steffy is. They rush downstairs and ask if Aly went to the airport to meet Thorne. They show Maya, Rick, Nicole, and Zende the disturbing altered photos. They talk about how Aly sees some people as good and some as bad. Liam wishes Steffy would get there. Ivy says Aly sometimes parks on the stretch of coast highway where her mom died. She'll go. Rick and Zende tell the story of how Darla was killed. No one is surprised Aly sees betrayal everywhere. Wyatt adds, "Especially in Steffy." Later, Zende and Nicole see off the guests. Rick wants them to stay and help with Aly when she gets there. Zende asks why Rick was such a bastard to her. Maya says they were wrong but her issues clearly go deeper than trouble at home.

Amid the clean-up after the fashion show at Forrester Creations, Maya and Rick show off her engagement ring to her parents, Nicole, and Brooke. Julius points out that Rick didn't ask him first - times have changed - but for the record he approves. Brooke takes Maya aside to express her approval. They embrace. Rick tells everyone the wedding will be as soon as possible and offers to take care of extending the Avant's airline tickets. They agree. When they step aside, Julius assures Vivienne he's rolling his eyes; he's just hiding it. All he knows is they have many more days ahead of drinking champagne. He mocks Rick for choosing Maya when he could have any real woman. Vivienne says she is a woman. Julius is just happy to marry off his embarrassing son and looks forward to reaping the rewards in L.A. Vivienne says he's not trying to accept her as he said. Julius thinks if he hangs around the California people he might become like them. Vivienne asks if he really believes that. Backstage, Wyatt, Liam, Steffy, and Ivy share a toast. Steffy invites Aly to join them and it doesn't go over well. She asks if she enjoyed the showstopper. Aly snaps, "Does it matter?" Aly moves behind a clothes rack and talks to the sinister floating head of Darla, who urges her to do something big to turn things around. "Do it tonight." In the group, Ivy says Aly has been darker lately and not just at work; she comes home and goes straight to her room. Steffy hopes she changes her mind and joins the party later. They talk business and Wyatt and Ivy go to put jewelry away. Steffy tells Liam that Ivy still thinks there's a chance. Liam meant what he said, he's committed to Steffy. Steffy tells him to let Ivy know after the party - she doesn't want anything to ruin the celebration. Outside in the parking lot, Aly punctures a sports car's tire. Steffy comes out and gets in it. Aly watches her drive away. Inside, Maya and Rick revel in their engaged status. Maya is glad she took the chance to tell him everything. He smiles. "It paid off."
